Photosynthesis is just a fancy word that describes how plants make their own food. photo means 'light' and synthesis means 'to put together'.
The three things that the plant "puts together" are sunlight, carbon dioxide, and water. When a plant receives these 3 things, something happens; an organelle in the cells of the plant called chloroplasts combine them and turn it into sugar in which the plant eats. Cool, huh?

Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
It is c commensalism that's the answer lol I can't spell it
